I've used three blades now. Firstly in my travel kit in a vintage Gillette English Flare Tip Rocket, then another in a vintage Gillette Slim (7) and most recently in a Gillette English NEW on a TSW Bren handle.
There have been some variables across these shaves but I've tried to keen some constants for at least a period to get comparisons.
First shave with the blade. Definitely a noticeable improvement over the standard Derby Extra. Gave a fairly good shave - not quite DFS, but certainly quite acceptable.
At $12.90 per 100 (
https://shavingmarket.com/shop/new-derby-premium-double-edge-razor-blades/) these are an inexpensive blade. Looking at price on shaving market, only an extra $1/100 over the Derby Extra, roughly 13c per blade so quite inexpensive.
Packaging is a plastic tuck with space for used blades - although the labelling is a little too 'try hard' for my taste. Made in Turkey they are made with premium Swedish steel and coated with chromium, ceramic, platinum, tungsten, and polymer - really? Again, sounds a little try hard. I was a sceptical.
Having said that - the proof is in the shave. My initial thoughts were that they were pretty good actually, relatively sharp and still smooth, with no tugging or pulling. In other words, doing what a blade should do!
Second and third shaves the same. Some sense of degradation on the fourth - have not pushed beyond there at this point. Certainly no irritation or really nasty stuff though and a step up from where I remember the Derby Extra to be (but that was a while ago). Decent middle of the road blade at a good price point.
Ratings for these blades to date below (out of five):
Value
- decent VFM at price point
Packaging
- yeah, it is packaging!
Smoothness
- above average for that 1-3 shave range
Sharpness
- average
Longevity
- probably around average for modern blades
Overall
- unlikely to be a star but will have some fans
Thanks AGAIN to
